What is the primary factor that determines whether a group is an ortho or para directing group in electrophilic aromatic substitution?

Options

  1. AThe group's size and steric hindrance
  2. BThe group's inductive effect
  3. CThe group's electronegativity
  4. DThe group's ability to donate or withdraw electron density

Correct answer

D. The group's ability to donate or withdraw electron density

Step-by-step solution

The group's ability to donate or withdraw electron density through resonance or inductive effects is the primary factor that determines whether it is an ortho or para directing group in electrophilic aromatic substitution.
